The angular dependence of the chemical shift of the 29Si nuclear magnetic resonance has been measured in a synthetic single crystal of Mg2SiO4 (space group Pbnm, Z = 4). The measurements were performed at room temperature at a frequency of 39.758 MHz using the FT-NMR technique. The eigenvalues of the shift tensor with respect to 29Si in TMS are δx = - 38.8 ppm, δv = -55.3 ppm and δz = - 95.4 ppm, with the eigenvector y parallel to c and the eigenvector z forming an angle of 7.5° with a. The results show clearly the influence of the individual S i - O bonds on the chemical shift tensor. The chemical shift along the S i -O bond depends in good approximation exponentially on the S i - O bond distance.

Hydrogen Bond Distance

A database study on the competition of hydrogen-bond acceptors for the strong carboxyl donor in crystals is reported. The relative success in attracting this donor is determined for 34 types of acceptor (O, N, S, halogen and π acceptors), and a correlation between the success in competition and the average hydrogen-bond distance is established.
